typenames

Simple node package to determine object types

Installation

npm install typenames

Usage

Basic Operation

Return the type of the an object

var typenames = require('typenames');

var t = typenames.typeOf("foo");

t = typenames.typeOf(new String("foo"));

Return the type name of an object

function bar () {}

var myObject = new bar();

console.log(typenames.typeOf(myObject)); // Object
console.log(typenames.typeName(myObject)); // bar

Custom objects need to implement the constructor pattern in order for the name to be identified.

Supported Types

The list below are the default types included.

typenames.string;
typenames.boolean;
typenames.bool;
typenames.number;
typenames.function;
typenames.array;
typenames.date;
typenames.regularExpression;
typenames.regexp;
typenames.object;
typenames.math;
typenames.json;
typenames.error;
typenames.arguments
typenames.null;
typenames.undefined;
typenames.error;
typenames.typeError;
typenames.symbol;

Comparison Operations

var d = new Date();
var bool = true;

var checkType = function(obj){
	switch(typenames.typeOf(obj)){
		case typenames.date:
			console.log('The date is ' + d)
			break;
		case typenames.boolean:
			console.log('bool');
			break;
		case typenames.object:
			console.log('Just an object');
			break;
		default:
			console.log('The object is a ' + typenames.typeOf(obj));
			break;
	}
}

checkType(d);
checkType(bool);
checkType('foo');

Custom objects will return a type of object. This can be used in conjunction with the typeName method to identify the object. An example is shown below.

function bar () {}

var myObject = new bar();

if(typenames.typeOf(moObject) == typenames.object){
	if(typenames.typeName(myObject) == bar.name){
		// True
	} else {
		// Another object	
	}
}
